Yep, I noticed this last year when they still stored the list client-side and had great fun reverse engineering it: twitter.com/moyix/status/14332542933527…

FYI, there is in fact a bad word filter in GitHub Copilot. When it was first released, the list was stored client-side in obfuscated form and I had a lot of fun decoding it: twitter.com/moyix/status/14332542933527… The Register wrote about it too: theregister.com/2021/09/02/github_copil…... They have since moved the bad word list server-side to prevent people from figuring out what's on it, but it's still there. This is easy to verify, just ask it to complete something that would include a banned word; my favorite here is "Israel", and it will just sit there and refuse to complete, either via inline suggestions or in the sidebar view that gives you 10 choices: i.imgur.com/O97YwKc.png This was what I managed to decode of the list (in ROT13 form to prevent accidental offense): moyix.net/~moyix/copilot_slurs_rot13.txt No doubt they've added and removed some things since then.

Someone on Twitter reverse engineered an earlier version of the list twitter.com/moyix/status/14332542933527… and the list linked somewhere in that thread contains "gender" (see news.ycombinator.com/context?id=32339001 for direct links).

There's a whole bad word list meant to suppress output. It's stored client side. twitter.com/moyix/status/14332542933527…...
